This Huia house kitchen, laundry and toilet plastering and painting works took two painters 3 visits to complete. This is a renovation painting job. The previous painter could not do new gib wall repair, plastering and sanding works. This is where we came in. We took over in the middle before it’s all completed.
We fixed all the damages, plastered smooth the major uneven surface, then we had to plaster the areas three times with the last time fine plastering and sanding to achieve smooth and even flat wall and ceiling surface so, after painting, people do not recognize that the walls and ceilings are completely repaired or replaced. These are the beginning of what they were:
It basically took one day for each layer of plastering. Before the next layer, we scratch and sand off the major sticks and marks then wait until the second and third coats dry for sanding. GIB wall plaster sanding is not a pleasant job, most trade people try to avoid that. As capable painters are not able to run away from this kind of sanding and plastering jobs, especially we are serving most of the restoration and renovation house owners.
These are the first coat of plastering: Top corners of the bathroom. Newly sealed new wall. A dome shape door which was sealed. Bathroom corner fixed.
Final touches: Even after the whole painting works, we constantly need to go back one more time for the so-called “final touches”. We make sure that we take utmost cares to finish all painting parts but it’s not avoidable that other people like electricians, cabinet installations, plumbers will do some extra damages on the wall and here and there during their repair or installation jobs.
It’s a good practice that we always save at least half a bucket of topcoat paint to achieve a satisfactory final painting result.
Low sheen for walls, flat paint for ceiling
Generally speaking, the interior wall is low sheen water-based paint; the ceiling is flat paint.
Ceilings have usually painted a light or white colour. Ceilings can be painted in a flat finish. Usually, the jams and baseboard are in a semi-gloss white light colour. The walls, in a colour different from the woodwork frame in a low sheen finish.
“One major difference of our professional painters is how we appreciate the concept and practice of priming” – Goldenland
Priming means applying special paint so that subsequent coats of paint adhere better. Only the sanded spots are primed, and the painted shingles are not primed at all. The final coat of paint, of course, covers all of the sidings. Therefore, “painting” is really two distinct steps: 1. applying primer paint to bare or repaired areas; 2. applying finish coat paint to the whole surface.
We sanded anything to bare wood, indoors or outdoors, and apply a primer before using paint. The primer contains less pigment, sinks in better for a more adhesive grip, and dries to a slightly granular texture. This rough surface allows subsequent paint coats to improve their grip on the wall so that they are less likely to peel in the future.
Primer is the first coat of paint put on unpainted surfaces. We use oil-based primer for bare wood, a rust inhibition primer for metal, a transparent masonry sealant for brick and concrete, and sealer for new drywall and plaster.
An existing coat of flat paint provides an adequately rough texture for a new coat to grip; glossy paint is roughed up in the preparation stage by hand sanding to take the sheen out and to create the tiny ridges and bumps to which the new paint can adhere.
Primer is usually white. This causes a colour consistency problem if the final coat of paint will be a dark colour the final coat may not completely cover the underlying white primer, leaving a streaked and irregular appearance. We have the primer tinted the approximate colour of the final coat. Painting over a dark colour or bright colour we use a primmer sealer such as a Dulux 1Step Prep. The primmer helps to seal out the dark or bright old colours. We can cover over a dark colour or bright colour with multiple coats of finish paint. However, the primer will save the cost limiting the number of finish coats you will have to apply.
